Re: crackling noise - help

I had this problem recently and I fixed it by correcting the latency buffer size (found under options - audio... - in sonar 7) - move the slider to the left (fast) side of the scale. Hope this helps.

Re: crackling noise - help

Check all your cords make sure they are connected proper if they are then its internal. Is the gear brand new if so its under warranty if not then come back and ask again. It takes a brave person to answer your direct email address that means you are able to see who the person is ie his email address you will know. On fixya people dont like emailing others because the others maybe spammers....hence the Report abuse button on this program!

Seem to have developed a problem with my audio recording and playback using Roland's FA-66 (Editrol). I use Cakewalk SONAR, Sony Sound Forge and Vegas Video softwares, and all of them show the same sound...

try these 2 sites, i believe they have some good info you need and will probably solve your issue. ive heard some horror stories about norton. unistall and see what comes about. it seems as though too many connections are going to screw this item up and norton will do the same.

Cakewalk Sonar - Edirol UA-1000 crackles on playback!

That's a latency issue it sounds like.
There's a slider under "Audio" .

Move it in increments towards "slow", test it as you go.
Leave it at the highest setting possible that doesn't crackle.

I've heard this so bad that it sounds like a gun going off.
It scares the Hell out of you when it happens !

Sonar LE: no playback b/c "NO MIDI OUTPUT" selected

You have to go in to the Sonar configuration and select what the default MIDI and WAV input and output devices are. That is usually handled by the ASIO driver. In your case you would select the USB mic for input, and for output you need to select your sound card. For midi you need to configure the midi controllers and the software synth or soft instrument you are using.
If you need any more detailed help I need to know what version of Sonar LE it is and what sound card. I am guessing it detected the mic and just needs the output device configured as I mentioned.

Crackling noise

I had the same problem initially. Upgrading the RAM from 1GB to 3GB seems to have done the trick in my case. Mind you, I also reinstalled Windows XP, so that could be another factor.

Crackling when recording with saffire

Without much info to go on I would first make sure that your input levels are not set too high when recording causing clipping and digital distortion on playback. Usually this is the thing that causes crackling sounds. Rather hard to fix after the fact and you may have to rerecord those tracks to get a cleaner sound you are happy with.

Microsoft re-engineered the audio bus for Windows. HD Audio is hardware specific, in the sense that specific drivers have to be written to make a piece of hardware compatible with it. Roland is not writing a driver for the UA 25 because they want you to buy an UA 25EX. Get my drift? The UA 25 uses Kernel Streaming, the old way, which exists in parallel, sort of, with the HD Audio bus. But the new ways are always prioritized over the old ways in software, so there is bus contention (glitching).

To fix this there are a few things you can try:

1) Roll back to SP2. SP3 implements the HD Audio bus, so don't use that implementation. If your laptop has an HD audio sound card then I doubt it would work, but your UA 25 would.

2) Try ASIO 4 ALL. This fixed everything but glitching in VST instruments.

3) Reduce the amount of stuff your computer is doing. Optimize your OS by turning off the cute shaded windows and desktops and various processes that you don't need to see or use. There are sites for this. This increases available RAM, CPU time, etc.

4) Video hardware acceleration, sometimes, would fix bugs in software left in by not so clever programmers.

4) You can always just give-up and go along with the bastards and buy new stuff and toss the old stuff.

Problem with playback

Hi, I have the same audio interface. Alright, make sure that all of your effects are turned off. you probably (and most likely) have the "fx voice", "amp drive", "chorus" and "delay" effects turned on (bottom row). There is no way you should have distortion with tremolo & reverb on playback all the same time without the effects being turned on. the pop ticking could be produced by the buffer size. If youre using Sonar LE, you should tweek the buffer size until playback sounds smooth. I hope I helped! Good luck!

Timing and noise

That's usually caused by problems with the usb port on your computer. The best solution would be to buy an PCI USB CARD that you would use only for your UAFX4.
